Juniper Networks Tells its Remarkable Optical Story at OFC17 in LA!
Apr 5, 2017
When Juniper Networks recently announced its latest Data Center Interconnect (DCI) solution, they decided this year’s Optical Fiber Conference (OFC)—the industry’s largest event for optical communications and networking companies—was the best place to amplify that message.
The new solution gives cloud providers, enterprises, and service providers the flexibility to interconnect data centers with a combination of high-capacity coherent DWDM optics and optimized routing, switching, virtualization, and network control technologies. (Details can be found on Juniper’s Open Cloud Interconnect web page.)
To support the announcement, Juniper’s Technical Marketing team was tasked with producing a demonstration that showcased the solution’s various components. Underscoring the company’s confidence in the quality and stability of its products, the demo was to be conducted live, with full IP/MPLS traffic running, for all five days of the conference.

Open Cloud Data Center Interconnect Demo
The demo was composed of two parts. First was the open cloud DCI solution, which included the following components:
The modular Juniper Networks QFX10008 data center spine and core Ethernet switch, which delivers industry- leading scale, flexibility, and openness powered by Juniper’s powerful and custom-designed Q5 ASIC supporting VxLAN routing.
An integrated six-port 100/150/200 Gbps coherent line card for Juniper Networks QFX10K, which interops with BTI Series Packet Optical Transport Platforms, MX Series 3D Universal Routers, and PTX Series Packet Transport Routers. The card, which offers 1.2T PFE with deep buffers, large FIB, full IP/MPLS support, and flex-rate modulation, is fully compatible in 200 Gbps mode with UFM6 on the BTI7800 line and in 100 Gbps mode with the DWDM MIC/PIC on the MX240 and PTX3000, as well as UFM3 on the BTI7800 line.
BTI7801 and BTI7802 optimized DWDM transport platforms with 400 Gbps/800 Gbps bandwidth, 96 channels, and support for UFM3/ UFM6 line cards.
UFM3 100 Gbps mux-ponder/transponder line cards with QPSK modulation, electric dispersion compensation, and interoperability with the MIC on the MX240.
UFM6 400 Gbps transponder line cards with 2x100/200 Gbps coherent DWDM ports and full C-band. The UFM6 interoperates with the integrated six-port coherent line card on the QFX10008.
Reliable, high-performance MX240 routers offering 1.92 Tbps of system capacity.
One-port 100 Gbps coherent DWDM MIC 100G MICs supported for the MX240, MX480, MX960, MX2010, and MX2020 platforms.
This part of the demo demonstrates how Juniper seamlessly interconnects data centers using a combination of optimized IP/MPLS routing and high-capacity optical networking gear integrated on routers and Ethernet switches, or operating in standalone BTI Series platforms. Traffic from the data center was channeled through the QFX10008. The traffic streams were converted into colored traffic by the DWDM coherent card, then sent through a 96-channel multiplexer to the BTI Series ROADM network. Traffic terminated on the DWDM coherent PIC on the MX240 platform, which routed it back to the remote data center.
Converged Metro Core Demo
The second part of the demo, as seen in the integrated topology shown in Figure 2 below, is the Converged Metro Core consisting of the following components:
Juniper Networks PTX3000 Packet Transport Routers.
The integrated photonics IPLC line card for the PTX Series, which combines a 1x2 WSS, embedded bi-directional switch gain amplifiers, optical multiplexer/de-multiplexers, and optical supervisory channels for optical management in a single package that supports up to 64 ITU-T C-band wavelengths at 50 Ghz spacing.
A five-port 100GbE coherent DWDM PIC with OTU4 (v) framing and DP-QPSK modulation with coherent reception.
An Optical Inline Amplifier (ILA) to provide bi-directional optical supervisory channel (OSC) and signal amplification. Works in conjunction with IPLC, a 64-channel mux/de-mux with integrated ROADM and amplifier, and with the 5x100 Gbps DWDM PIC, providing a simple, end-to-end packet optical solution.
The ExpressPlus-based FPC3, based on the custom-built ExpressPlus chipset, offering 10x100/10x40/40x10GbE speeds in its PTX3000 version.
Figure 2: Converged Metro Core demo overview.
As in the DCI part of the demo, live traffic was sent through the metro core. In this case, the demo showed how optical gear, integrated in core routers as pluggable line cards, can connect extended metro cores, with the option to use ILAs for long-haul use cases. Traffic was sent from a traffic generator in the data center through PTX3000, where DWDM-coherent PICs map gray to colored traffic of multiple wavelengths. Traffic is then sent through the IPLC card to the remote site—in this case another PTX3000—through a single fiber. The ILA was deployed in between PTX3000 routers, simulating long-haul scenarios.
proNX Service Manager (PSM)
Another major component that was demonstrated at the conference was Juniper Networks proNX Service Manager (PSM), which provides complete, end-to-end visibility into the network. PSM also provides alarm reporting and PM information, allowing customers to configure network parameters on different levels, including ports, channels, and wavelengths. All nodes in the demo were managed by PSM, enabling real-time monitoring and centralized control.
At the Show
The blinking lights on our demo equipment on the OFC17 show floor indicated live traffic was flowing. This activity was a real eye catcher for customers and booth visitors, especially since Juniper was the only major exhibitor presenting a live demo at this year’s event!
Figure 3: Juniper’s booth with live demo drew many visitors.
It was interesting to see people’s reaction to, and curiosity about, the demo. Visitors were particularly interested in the new products that Juniper had announced at the show, and the Juniper team was busy throughout the conference answering questions and providing details about our solutions.
In addition to the DCI demo, Juniper also participated in the Ethernet Alliance (EA) interop demo at OFC17, demonstrating our ability to interoperate with other vendors running various Ethernet speeds.
All in all, OFC17 was a remarkable event, and it was a pleasure to demonstrate our DCI solution and highlight our optical story. It was a welcome opportunity to address the challenges of vendor lock-ins, operational silos, and interoperability risks through our open, programmable, and quality-driven products.

Thank you to the wonderful Juniper OFC17 team, and all people who contributed to the success of the event.
We are already looking forward to OFC18 in San Diego next year!
